摘要: Patients infected with the human immunodeficiency virus experienced severe hematopoietic toxicity after treatment deoxynucleoside analog 3'-fluorothymidine (FLT). Using several methods for analysis of genome integrity, including histochemical staining 3' ends DNA and both conventional pulsed-field agarose gel electrophoresis, we demonstrated that FLT caused extensive fragmentation in CEM cells was not observed when these were treated other, less toxic thymidine analogs. In addition, a distinctive pattern small fragments is characteristic process programmed cell death genomic FLT. We conclude induces apoptosis line origin, offer this observation as possible explanation vivo.
